Distilling plant systems

Distilling plants are found aboard many vessels to produce potable, or drinking water, from seawater during voyages. Also known as evaporators, these plants reduce the need to use cargo space for freshwater. Distilling plants also ensure vessel drinking water is fresh, as stored water is subject to contamination or spoiling when in stowage. The process of distillation involves evaporation and condensation. Raw seawater is heated, water particles vaporize leaving behind salt particles, the pure water vapor is then condensed and circulated to various freshwater sources throughout the vessel.
